SIP Proxy Server Service Control Logic Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional SIP systems lack the capability to provide diversified services and control service execution, failing to meet user requirements for advanced multimedia communication.
Innovation Solution
A SIP service enhancement method and proxy server that receive and parse SIP requests to obtain service control logic, loading and executing service process description information to deliver specific services to users, utilizing BPEL4SIP or other languages to manage service logic and interact with participants and content gateways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional SIP proxy servers are used for basic session routing, then the system structure remains simple, but the system cannot provide diversified services or control service execution
Solution Approach 1:
The SIP proxy server is enhanced with a service processing unit that can execute multiple types of services through a unified service control logic interface. The service processing unit parses service IDs from SIP requests, loads corresponding service process descriptions, and executes the appropriate service control logic, enabling the same proxy server structure to provide diverse services such as call forwarding, conferencing, and messaging without requiring separate specialized servers for each service type.
2Adaptability or versatility
If service control logic is added to the SIP proxy server to enable service execution, then diversified services can be provided, but the device complexity increases
Solution Approach 1:
The enhanced SIP proxy server is divided into distinct functional modules: the original SIP transfer interface unit for message routing, and a newly added service processing unit with sub-components including a service control logic parsing unit (which further divides into service ID parsing, service process description loading, and service control logic extraction) and a service executing unit. This segmentation allows each component to have a specific, well-defined function, making the overall complex system manageable and maintainable through modular design.
3Reliability
If service process description information is stored and parsed, then accurate service control logic can be obtained, but information processing time increases
Solution Approach 1:
Service process description information is pre-formatted and stored in a standardized structure in the service process description database before being needed. When a service request arrives, the service control logic parsing unit can quickly parse the pre-structured information using template matching and predefined parsing rules, rather than having to interpret unstructured or complex service definitions in real-time. This preliminary preparation of service descriptions significantly reduces the time required to extract service control logic while maintaining high accuracy.

AI summary
A service enhancement method includes: receiving a Session Initiation Protocol (SIP) request for using a service from a SIP user, obtaining service control logic according to the SIP request; and executing the service control logic to deliver the service to the SIP user.
